On August 13, 2019, The U.S. Patent Office granted US Patent No. 10,378,838 to the Hush Puppy Project for its Slide Lock Device (“SLD”). Hush Puppy Project is a Louisiana-based manufacturer of suppressors, pistols and ammunition “dedicated to the art and science of small arms signature reduction.” US Patent No. 10,378,838 is directed to a mechanism that converts a semiautomatic pistol’s self-loading system to a single-shot locked breech mechanism, thus eliminating the mechanical sound of the slide cycling, the emission of noise from the ejection port (“port pop”) and collateral sound from brass hitting the ground while allowing the suppressor to achieve maximum efficiency. With the SLD disengaged, the pistol may still be fired in normal semiautomatic mode.
“Our new SLD patent covers the mechanism that converts a Glock pistol to function in locked breech mode, thus making for the quietest shot possible, especially when combined with the Hush Puppy Model 2 wipe silencer and Super Vel Mk 144 subsonic ammunition.” said Brad Gilpin, Hush Puppy Project president.
The Hush Puppy Project currently manufactures two brands of pistols with SLDs, Glock 19 Gen 5 and S&W M&P 2.0 as well as two suppressors, the Model 1 and Model 2. Super Vel Ammunition, a sister company of the Hush Puppy Project, manufactures subsonic 9mm ammunition as part of the Project’s “systems approach” to sound reduction.
Hush Puppy Project guns, suppressors and ammunition are available exclusively from Lipsey’s, a firearms wholesaler servicing stocking gun dealers. Military and Law Enforcement customers are manufacturer direct. The Hush Puppy Project is located in Baton Rouge, La.
